Perhaps some preachers do talk too much about money - although in my experience they are in the minority. If you think your concern is legitimate, you have a responsibility to speak to your pastor or your church's officers about it.
However, God's work requires financial support, and it isn't wrong for your church's leaders to inform the members about their church's financial needs. Even Jesus' band of 12 disciples had a treasurer, and we read of some women of wealth who "were helping to support them out of their own means" (Luke 8:3). On more than one occasion, Paul wrote about the financial needs of the churches, and urged people to give sacrificially and joyously (e.g., 2 Corinthians 8:1-7).
Let me ask you a question: Have you ever asked yourself why you're so opposed to any talk about giving? Could it be that you have never yielded every area of your life to Christ - including your money? Be honest before God - and then ask Him to help you commit everything you are and everything you have to Christ. Remember: He gave His all for you - even His life.
Jesus warned, "No one can serve two masters. ... You cannot serve both God and Money" (Matthew 6:24). Put Christ first in your life, and then ask Him to use both you and your money for the spread of His Kingdom.
